in response to 3systemuser...wow,sour grapes maybe?"EVEN 5D3 BETTER THAN D600",i'm a nikon shooter and have shot the 5d3..awesome camera,d600 matches it for image quality,build quality,speed,af,responsiveness are excellent on 5d3..best in class compared to d800 and sony a99.d600 for its price point is an excellent "entry" ff camera and will compete very well with canon's not yet released 6d..which i expect to be an excellent "entry"level ff...as for me cant wait to pick up my "inferior almost useless d600".cheers
